Looks like Sprint is pushing some OTA updates to a couple of all-but-forgotten devices: the LG Marquee and the Kyocera Echo. We haven't really heard much about the Marquee since it was announced back in September, but it appears that Sprint hasn't forgotten about it. A minor OTA update should be rolling out to the Marquee right now that brings a couple of bug fixes:

Device may lockup while on call

Security Update

Similarly, that quirky little dual-screened oddity known as the Kyocera Echo is also on the receiving end of a minor update that fixes some issues:

MMS audio cuts off after 8 seconds

Changes to roaming guard display

Activation of Commercial Mobile Alert System

Security Update

It's probably safe to assume that the security update portion of both OTAs is the removal of Carrier IQ, which Sprint has been removing from all of its devices over the last several weeks.
